Transmission Control Valve Body Overhaul Notice
WARNING: This page is about a different car, the 2007 GMC Sierra and 2007 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- Transmission damage may occur when control valve assembly springs and other parts are mistakenly interchanged. Interchanging parts can be avoided by observing the following precautions:
- Tag each part immediately when removed.
- Use J 33163 Valve Tray Set to organize parts and to simplify correct valve body reassembly.
- Protect control valve assembly parts from damage by observing the following precautions:
- Handle all valves carefully.
- Protect control valve assembly parts during removal, cleaning, inspection, and assembly.
- Keep the parts in a clean container until the parts are installed.
- When a valve is installed dry, the weight of the valve is sufficient to move the valve through the valve bore. If a valve does not move freely, the transmission may be damaged.
